Wisconsin has designated many of the state's highest quality waters as Outstanding Resource Waters (ORWs) or Exceptional Resource Waters (ERWs). Waters designated as ORW or ERW are surface waters which provide outstanding recreational opportunities, support valuable fisheries and wildlife habitat, have good water quality, and are not significantly impacted by human activities. ORW and ERW status identifies waters that the State of Wisconsin has determined warrant additional protection from the effects of pollution. These designations are intended to meet federal Clean Water Act obligations requiring Wisconsin to adopt an 'antidegradation' policy that is designed to prevent any lowering of water quality - especially in those waters having significant ecological or cultural value.

A water is polluted or 'impaired' if it does not support full use by humans, wildlife, fish and other aquatic life and it is shown that one or more of the pollutant criteria are not met.

Overview

Un Lake, in the Little Lake Butte des Morts Watershed, is a 1.45 acre lake that falls in Winnebago County. This lake is managed for fishing and swimming and is currently not considered impaired.

Condition

Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water quality monitoring program uses a tiered approach to analyze compliance with Clean Water Act fishable, swimmable standards. The Executive Summary of Water Condition in 2014 is available. See also 'monitoring' and 'projects'.

Management Goals

Wisconsin's Water Quality Standards (State Administrative Code NR 102) provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable.

Management goals can include creation and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.

Monitoring

Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy is in the process of a major update in 2014.

Watershed Characteristics

Unnamed is located in the Little Lake Butte des Morts watershed which is 43.77 mi². Land use in the watershed is primarily agricultural (31.58%), suburban (29.47%) and a mix of urban (21.24%) and other uses (17.71%). This watershed has 60.88 stream miles, 74.47 lake acres and 848.70 wetland acres.

Nonpoint Source Characteristics

This watershed is ranked high for streams, not available for lakes and high for groundwater and therefore has an overall rank of high. This water is not ranked for pollution runoff.
